Iodine is a vital trace element. Iodine, as Iodide, Iodate and organic Iodine may be the most rapidly depleted trace element utilized in a marine aquarium. Iodine may also contribute to coral coloration, growth and general health. The natural seawater concentration of Iodine is approximately .06ppm.

Iodine levels must be regularly tested, as low levels may damage many corals.

Reef Pure Concentrated Iodide Supplement is the most effective way of adding Iodide to the marine aquarium.

ReefPure Concentrated Iodide Supplement may be dosed continually or added 2-3 times per week.
